Open SDK: Build custom workflows or integrate with third-party systems for automation and AI-based analysis.
Hydrophones: Underwater Surveillance & Submarine Detection
In the realm of underwater intelligence and maritime security, hydrophones play a critical role in capturing acoustic data beneath the surface. These specialized microphones are designed to detect and record sound waves underwater, making them indispensable for submarine detection, coastal surveillance, and environmental monitoring.
At John Barry, we offer a range of professional-grade hydrophones from Ambient Recording, trusted by audio engineers and defence professionals alike. Our lineup includes:
Ambient ASF-2 MKII Compact Hydrophone
Designed for underwater applications up to 30 metres, this hydrophone features a frequency range of 70Hz–20kHz, ideal for capturing a wide spectrum of underwater sounds while minimizing low-frequency cable noise. Its anodized aluminium housing and watertight polyurethane cable make it suitable for rugged marine environments. Powered by 48V phantom, it integrates seamlessly with professional field mixers and recorders.
Ambient ASF-1 MKII Soundfish Hydrophone
A premium option for professional underwater recording, the ASF-1 MKII offers enhanced sensitivity and durability. It’s ideal for long-term acoustic monitoring, underwater ordnance tracking, and naval research.
These hydrophones are increasingly used in submarine surveillance, where passive acoustic monitoring is essential for detecting underwater movement without revealing one’s own position. In addition, they support environmental studies, such as marine life tracking and oceanographic research, making them versatile tools for both defence and scientific applications.
Emerging technologies like MEMS-based hydrophones are also gaining traction, offering low-cost, high-sensitivity solutions for scalable deployment across fleets, buoys, and autonomous underwater vehicles (AUVs).
Whether you’re outfitting a naval vessel, conducting coastal reconnaissance, or deploying underwater sensors, our hydrophone range provides the precision and durability needed for modern maritime operations.
